Not too easy. Not too difficult.
The course seems like it will be a breeze... You're allowed open notes on the exams. Don't be tricked! The exams are super intense and time restricted. If you don't prepare you will not do well.
You learn a bit about the human body which is pretty cool. Most of it is kind of self explanatory if you have a deep biology background (which you likely do if you meet the pre-reqs).

Advice for students:
Study hard! The course doesn't have much on Course Hero, don't wait til the last minute.
